[0001] This invention is generally related to lamp shades, and more particularly to a removable,
universal, foldable lamp shade overshade.
[0002] The construction of conventional lamp shades is well known and typically require
replacement long before the lamp itself is either worn or desired to be replaced for
decorative considerations. However, in replacing a conventional lamp shade, both size
and decorative considerations become somewhat restrictive in selecting a replacement.
[0003] Additionally, seasonal or festive considerations may make it desirable to temporarily
alter the appearance of one or more lamp shades in a room or home setting.
[0004] One such device for accomplishing this is disclosed in U.S. Patent 4,731,715 to Anderson
which is directed to a conformable covering fabricated from a rectangular swath of
cloth which may be fitted over a conventional lamp shade.

However, none of these references are of a nature similar to that of the present
invention.
[0006] The present invention provides a universal, foldable lamp shade overshade which may
be manufactured from any convenient semi-rigid decorative material which is formed
into a uniformly pleated rectangular sheet bendable primarily about the fold lines
between each slender panel in accordion fashion. This structure includes a drawstring
adjacent the upper end and has sufficient pliability about the fold lines so as to
conform to a broad range of lamp shade sizes of perimeters and lengths and shapes.
Moreover, the device is structured so as to rest atop a tapered lamp shade held thusly
primarily by gravity, requiring no additional connecting means between the device
and the lamp shade. Compact storage is also provided.
[0007] This invention is directed to a universal foldable lamp shade overshade which includes
a uniformly pleated rectangular sheet of thin, somewhat rigid yet bendable material
having a plurality of side-by-side slender elongated panels integrally connected one
to another in accordion fashion along a fold line between each panel. A hole is formed
through each panel adjacent its upper end through which a draw string is positioned
in in-and-out fashion through alternate holes. The side margins of the pleated sheet
are connected to form a somewhat tubular member which is sized, when reduced in circumference
at its upper end by tightening the drawstring, to be held in place primarily by gravity
over and substantially covering a lamp shade.
[0008] It is therefore an object of this invention to provide a universal, foldable lamp
shade overshade which may be fabricated from a virtually limitless selection of semi-rigid,
bendable decorative materials.
[0009] It is another object of this invention to provide a universal lamp shade overshade
which will decoratively cover a conventional lamp shade, thus providing a completely
different decorative lamp shade appearance without the need for lamp shade replacement.
[0010] It is yet another object of this invention to provide a universal lamp shade overshade
which is expandable to fit over and cover a very broad range of lamp shade sizes of
perimeters and lengths and shapes.
[0011] It is yet another object of this invention to provide a universal lamp shade overshade
which may substantially alter the decorative length configuration of a conventional
lamp shade.
[0012] It is yet another object of this invention to be compactly storable.
[0013] In accordance with these and other objects which will become apparent hereinafter,
the instant invention will now be described with reference to the accompanying drawings.
[0014] Figure 1 is a perspective view of the preferred embodiment of the invention in its
relaxed configuration.
[0015] Figure 2 is an exploded view of the invention shown in Figure 1 fitted over a conventional
lamp shade.
[0016] Figure 3 is a section view in the direction of arrows 33 in Figure 1.
[0017] Figure 4 is a section view similar to Figure 3 showing an alternate connecting means
between the free side margins of the pleated rectangular sheet.
[0018] Figure 5 is a view in the direction of arrows 5-5 in Figure 2.
[0019] Figure 6 is a view similar to Figure 5 in conjunction with an irregularly shaped
lamp shade.
[0020] Figure 7 is an end view of the invention in its stored configuration and showing
yet another configuration for connecting the side margins of the pleated sheet.
[0021] Referring now to the drawings, and particularly to Figure 1, the preferred embodiment
of the invention is shown generally at numeral
10̸. This overshade
10̸ is fabricated of a pleated sheet
12 formed of relatively stiff, yet foldable decorative material sufficiently rigid so
as to maintain a free-standing shape as shown in Figure 1, yet sufficiently pliable
so as to be expandable in accordion fashion.
[0022] Referring additionally to Figure 3, edge panels
28 and
30̸ of pleated sheet
12 are overlapped and adhered together along surface
32 by conventional adhesive, double-sided adhesive tape, or the like so as to form the
generally tubular-shaped member depicted in Figure 1.
[0023] A drawstring
14 formed of a length of thin, flexible cord material is positioned in in-and-out fashion
through holes formed adjacent the upper margin
24 of the pleated sheet
12. The ends
20̸ and
22 of drawstring
14 exit through adjacent holes at
16 and
18 so as to be tightenable and tieable after suitably reducing the circumference of
the upper end
24 of the tubular-shaped pleated sheet
12. Alternately, the flexible cord
14 may be elastic and continuous.
[0024] Referring additionally to Figure 2, the overshade
10̸ is shown having drawstring
14 tensioned so as to have reduced the circumference of upper margin
24 ready for slidable fitting downwardly over a conventional lamp shade
L. No further preparation is required to fit the device
10̸ in snug position over and substantially or fully covering the lamp shade
L. Because most lamp shades are tapered upwardly, coupled with the tensioning and securing
of drawstring
14, the device
10̸ will remain in position decoratively covering the lamp shade
L, aided primarily by the force of gravity and surface friction between the inner surface
of the device
10̸ and the outer surface of lamp shade
L.
[0025] Referring now to Figure 4, an alternate embodiment of the connecting means between
the edge panels
28 and
30̸ of the pleated sheet
12 is there depicted at
10̸′. This connecting means is in the form of a U-shaped metal or plastic clip
36 having opposing inwardly projecting barbs
38 and
40̸ which pierce through the corresponding layers of overlapping pane! material to secure
and maintain the tubular shape.
[0026] Referring now to Figures 5 and 6, the compliability of the embodiments
10̸ and
10̸′ of the invention around irregular shaped lamp shades
L and
L′ each having its own distinctively shaped upper and lower margins
N and
M or
N′ and
M1′ is there shown. Thus, from the standpoint of both size and shape accommodation,
either embodiment of the invention
10̸ or
10̸′ is fully capable of expanding as required and exhibiting sufficient pliability so
as to generally maintain the overall shape of the lamp shade
L or
L′.
[0027] Moreover, the length of the tubular member
12 may be selected so as to be substantially longer than the height of the lamp shade
and drawstring
14 may be tensioned such that either the upper margin
24 or the lower margin
26 may extend either above, or below, the upper or lower margins, respectively of a
lamp shade. Because of the relatively stiff nature of the pleated sheet, the overall
tubular shape, in the form of a truncated cone as in Figure 2, will uniformly extend
the existing shape of the lamp shade itself so as to alter the decorative impact thereof.
[0028] Referring lastly to Figure 7, the invention is shown in another alternate form at
10̸′′ in its fully folded or stored configuration. In this embodiment
10̸′′, the same pleated sheet
12 is adhered along overlapping edge panels
28 and
30̸ and the panel adjacent to each so as to increase the overall strength of the tubular
shape.
[0029] While the instant invention has been shown and described herein in what are conceived
to be the most practical and preferred embodiments, it is recognized that departures
may be made therefrom within the scope of the invention, which is therefore not to
be limited to the details disclosed herein, but is to be afforded the full scope of
the claims so as to embrace any and all equivalent apparatus and articles.
